FIG. 3 isa schematic diagram illustrating an embodiment of a radio protocolarchitecture of a user plane 350 and a control plane 300. In FIG. 3 ,the radio protocol architecture for a first communication node (UE, gNBor an RSU in V2X) and a second communication node (gNB, UE or an RSU inV2X), or between two UEs is represented by three layers, which are alayer 1, a layer 2 and a layer 3 , respectively. The layer 1 (L1) is thelowest layer and performs signal processing functions of various PHYlayers. The L1 is called PHY 301 in the present disclosure. The layer 2(L2) 305 is above the PHY 301, and is in charge of the link between afirst communication node and a second communication node, as well as twoUEs via the PHY 301. L2 305 comprises a Medium Access Control (MAC)sublayer 302, a Radio Link Control (RLC) sublayer 303 and a Packet DataConvergence Protocol (PDCP) sublayer 304. All the three sublayersterminate at the second communication node. The PDCP sublayer 304provides multiplexing among variable radio bearers and logical channels.The PDCP sublayer 304 provides security by encrypting a packet andprovides support for a first communication node handover between secondcommunication nodes. The RLC sublayer 303 provides segmentation andreassembling of a higher-layer packet, retransmission of a lost packet,and reordering of a data packet so as to compensate the disorderedreceiving caused by HARQ. The MAC sublayer 302 provides multiplexingbetween a logical channel and a transport channel. The MAC sublayer 302is also responsible for allocating between first communication nodesvarious radio resources (i.e., resource block) in a cell. The MACsublayer 302 is also in charge of HARQ operation. The Radio ResourceControl (RRC) sublayer 306 in layer 3 (L3) of the control plane 300 isresponsible for acquiring radio resources (i.e., radio bearer) andconfiguring the lower layer with an RRC signaling between a secondcommunication node and a first communication node device. The radioprotocol architecture of the user plane 350 comprises layer 1 (L1) andlayer 2 (L2).

FIG. 4 is a block diagram of a first communicationdevice 410 and a second communication device 450 that are incommunication with each other in access network.

The first communication device 410 comprises a controller/ processor475, a memory 476, a receiving processor 470, a transmitting processor416, a multi-antenna receiving processor 472, a multi-antennatransmitting processor 471, a transmitter/receiver 418 and an antenna420.

The second communication device 450 comprises a controller/ processor459, a memory 460, a data source 467, a transmitting processor 468, areceiving processor 456, a multi-antenna transmitting processor 457, amulti-antenna receiving processor 458, a transmitter/receiver 454 and anantenna 452.

In the transmission from the first communication device 410 to thesecond communication device 450, at the first communication device 410,a higher layer packet from the core network is provided to a controller/processor 475. The controller/processor 475 provides a function of theL2 layer. In the transmission from the first communication device 410 tothe first communication device 450, the controller/processor 475provides header compression, encryption, packet segmentation andreordering, and multiplexing between a logical channel and a transportchannel, and radio resources allocation to the second communicationdevice 450 based on various priorities. The controller/processor 475 isalso responsible for retransmission of a lost packet and a signaling tothe second communication device 450. The transmitting processor 416 andthe multi-antenna transmitting processor 471 perform various signalprocessing functions used for the L1 layer (that is, PHY). Thetransmitting processor 416 performs coding and interleaving so as toensure an FEC (Forward Error Correction) at the second communicationdevice 450, and the mapping to signal clusters corresponding to eachmodulation scheme (i.e., BPSK, QPSK, M-PSK, M-QAM, etc.). Themulti-antenna transmitting processor 471 performs digital spatialprecoding, including codebook-based precoding and non-codebook-basedprecoding, and beamforming on encoded and modulated symbols to generateone or more spatial streams. The transmitting processor 416 then mapseach spatial stream into a subcarrier. The mapped symbols aremultiplexed with a reference signal (i.e., pilot frequency) in timedomain and/or frequency domain, and then they are assembled throughInverse Fast Fourier Transform (IFFT) to generate a physical channelcarrying time-domain multi-carrier symbol streams. After that themulti-antenna transmitting processor 471 performs transmission analogprecoding/beamforming on the time-domain multi-carrier symbol streams.Each transmitter 418 converts a baseband multicarrier symbol streamprovided by the multi-antenna transmitting processor 471 into a radiofrequency (RF) stream. Each radio frequency stream is later provided todifferent antennas 420.

In the transmission from the first communication device 410 to thesecond communication device 450, at the second communication device 450,each receiver 454 receives a signal via a corresponding antenna 452.Each receiver 454 recovers information modulated to the RF carrier,converts the radio frequency stream into a baseband multicarrier symbolstream to be provided to the receiving processor 456. The receivingprocessor 456 and the multi-antenna receiving processor 458 performsignal processing functions of the L1 layer. The multi-antenna receivingprocessor 458 performs receiving analog precoding/beamforming on abaseband multicarrier symbol stream from the receiver 454. The receivingprocessor 456 converts the baseband multicarrier symbol stream afterreceiving the analog precoding/beamforming from time domain intofrequency domain using FFT. In frequency domain, a physical layer datasignal and a reference signal are de-multiplexed by the receivingprocessor 456, wherein the reference signal is used for channelestimation, while the data signal is subjected to multi-antennadetection in the multi-antenna receiving processor 458 to recover anythe second communication device-targeted spatial stream. Symbols on eachspatial stream are demodulated and recovered in the receiving processor456 to generate a soft decision. Then the receiving processor 456decodes and de-interleaves the soft decision to recover the higher-layerdata and control signal transmitted on the physical channel by the firstcommunication node 410. Next, the higher-layer data and control signalare provided to the controller/processor 459. The controller/processor459 performs functions of the L2 layer. The controller/processor 459 canbe connected to a memory 460 that stores program code and data. Thememory 460 can be called a computer readable medium. In the transmissionfrom the first communication device 410 to the second communicationdevice 450, the controller/ processor 459 provides demultiplexingbetween a transport channel and a logical channel, packet reassembling,decryption, header decompression and control signal processing so as torecover a higher-layer packet from the core network. The higher-layerpacket is later provided to all protocol layers above the L2 layer, orvarious control signals can be provided to the L3 layer for processing.

In the transmission from the second communication device to the firstcommunication device, at the second communication device 450, the datasource 467 is configured to provide a higher-layer packet to thecontroller/processor 459. The data source 467 represents all protocollayers above the L2 layer. Similar to a transmitting function of thefirst communication device 410 described in the transmission from thefirst communication device 410 to the second communication device 450,the controller/processor 459 performs header compression, encryption,packet segmentation and reordering, and multiplexing between a logicalchannel and a transport channel based on radio resources allocation soas to provide the L2 layer functions used for the user plane and thecontrol plane. The controller/processor 459 is also responsible forretransmission of a lost packet, and a signaling to the firstcommunication device 410. The transmitting processor 468 performsmodulation mapping and channel coding. The multi-antenna transmittingprocessor 457 implements digital multi-antenna spatial precoding,including codebook-based precoding and non-codebook-based precoding, aswell as beamforming. Following that, the generated spatial streams aremodulated into multicarrier/single-carrier symbol streams by thetransmitting processor 468, and then modulated symbol streams aresubjected to analog precoding/beamforming in the multi-antennatransmitting processor 457 and provided from the transmitters 454 toeach antenna 452. Each transmitter 454 first converts a baseband symbolstream provided by the multi-antenna transmitting processor 457 into aradio frequency symbol stream, and then provides the radio frequencysymbol stream to the antenna 452.

In the transmission from the second communication device 450 to thefirst communication device 410, the function of the first communicationdevice 410 is similar to the receiving function of the secondcommunication device 450 described in the transmission from the firstcommunication device 410 to the second communication device 450. Eachreceiver 418 receives a radio frequency signal via a correspondingantenna 420, converts the received radio frequency signal into abaseband signal, and provides the baseband signal to the multi-antennareceiving processor 472 and the receiving processor 470. The receivingprocessor 470 and multi-antenna receiving processor 472 collectivelyprovide functions of the L1 layer. The controller/processor 475 providesfunctions of the L2 layer. The controller/processor 475 can be connectedwith the memory 476 that stores program code and data. The memory 476can be called a computer readable medium. In the transmission from thesecond communication device 450 to the first communication device 410,the controller/processor 475 provides de-multiplexing between atransport channel and a logical channel, packet reassembling,decryption, header decompression, control signal processing so as torecover a higher-layer packet from the UE 450. The higher-layer packetcoming from the controller/processor 475 may be provided to the corenetwork.
